It says:
"[jon at localhost ~]$ ll /bin/su
-rwxr-xr-x  1 jon root 59740 Jul 25 17:39 /bin/su"

I've tried typing my password slowly, checking my keyboard layout,
changing password, _removing_ the password from /etc/shadow and creating
a new one, but alas. I just get "incorrect password" from the terminal.
